-J r.-, a citizen of the United States, residingin the city and countyofSan Francisco, State of California,'hav e invented certain new anduseful Improvements in StreaImDeflectors';

full, clear, and exact description of t e same: Inconnection withnozzles for directing an impact stream onto the'buckets' of a tangent'awater wheel or hydraulic motors it is ans tomary to employ what istermed a deflec-' tor for the purpose of deflecting. a portion 'oftheimpact stream off of the motor, such deflection being in accordancewith-load a-v riations of the motor,1 tha't isto say, where themotors'load is reduced, the deflector out" into the issuing impactstream and deflect such a quantity of'the said stream as to leave,

only such a I 1 motor as will suflice for the required working load.With the deflectors or the common type, avery heavy efl'prt is requiredtokeep ortion thereof to bearonto the the deflector, when it starts tocut into the stream,f'r0m unbalanced force tending to pull the sametherem. It follows,-thatby the use of such a defiector'forregulating thespeed or power output of a hydraulic motor, as for instance.

a water wheel, that means must be provided which will hold the deflectorin every and any position, hencea' heavy and constant load oei'ng thusplaced onto the holding means,

usually the governor-for the motor, when the motor is in operation, insomeinstances this load reachingmany thosuands of pounds, requiring theintroduction ofvery expensive control-ling mechanism, making itdifficult to handle sucha deflector byhandpower, if

for any'reason the controlling mechanism is outvof commission.

The objectof the )resent'mvention'is to provide astreaffirle ector forWater Wheels or hydraulic motors of largepower, which may be controlledby less complicated and cheaper means than at present required t;

operate and hold the same against the pres- J sure exerted thereon, orwhich may be con? trolled byhand power, if-for any reason the operatingmechanism be thrown out of-commission, the deflector for attaining suchobject being so shaped as to utilize the reactory pressure of the wateron the surface thereof to counterbalance the water. pressure which tendsto force the same intothe stream.

Various 'inod" cations and combinations IO of-the curves for the.deflector platemay' be utilized the .onlyrequirement being that thewater to be-deflected be received at an angle to its line of flow, so asto cause the deflected strearnvto react as it flows over the discharge 15 surface; of the deflector late, in order that a reaction-pressure maye obtained to counadvance of the nozzle, of mechanism for aco,- tuatingthe deflector, and said deflector havin a discharge-surface shaped tocounterbalance the forces that exist to force the deflector in thedirection of its movement into ,the nozzle stream. v

4.. The combination with a hydraulic nozzle,of a stream deflectormounted to swing in advance of the nozzle, the same having a re ceivingand discharge surface both of which surfaces extend rearwardly relativeto said nozzle.

5. A deflector attachment for hydraulic nozzles having a receivingportion, and a (llS- charge portion, the discharge portion beingarranged in opposition to the receiving portion. I

6. The combination with a hydraulic nozzle of a cut-off or deflectorconnected to the nozzle and arranged to deflect a portion of 'the streamissuing from the nozzle, and a counteracting discharge portion on saidde- "flector.

7. The combination with a nozzle of a plate for deflecting a portion ofthe stream issuing therefrom, said plate having a receiving surface anda balancing surface constructed and arranged so that the pressure of thewater on the latter tends to neutralize the pressure on the former.
